Radeon RX 6900 XT vs Radeon Vega Frontier Edition
Intro
The Radeon RX 6900 XT uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this card. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.Compare those specifications to the Radeon Vega Frontier Edition, which comes with core speeds of 1382 MHz on the GPU, and 1890 MHz on the 16384 MB of HBM2 RAM. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
